Bug #757749 – Using ALTER TABLE to convert an InnoDB table to a MEMORY table could fail due to a bug in innodb_expand_fast_index_creation.patch. (Alexey Kopytov)

Bug #764395 – InnoDB crashed with an assertion failure when receiving a signal on pwrite(). The problem was that InnoDB I/O code was not fully conforming to the standard on POSIX systems. Calls to fsync(), pread(), and pwrite() can be interrupted by a signal. In such cases, InnoDB would crash with an assertion failure, rather than just restarting the interrupted call. (Alexey Kopytov)

Bug #766236 – A crash was occurring in some cases when innodb_lazy_drop_table was enabled with very large buffer pools. (Yasufumi Kinoshita)
